[@mikef-gi2dg]

Watched this again. They seem to be right where they were intended to run, 700hp + -. According to the hp and torque curves, the dip in the boost matches the peak on the torque curve. The sweet spot in torque/ rpm for the engine. The supercharger says, I'm pushing the flow regardless of size, try to keep up. Nice.

[@EGGINFOOLS]

That smaller pulley would have probably made more peak power on that 4.8.

[@wyattwunderlin4445]

This is a great test demonstrating that boost levels do not correlate to horsepower when comparing different engines. Also, it is important to note that you cannot just "pulley up" a small supercharger and expect it to make large gains in power. Each supercharger has to be sized to the correct application with expected air demands and supercharger speed. Also to note, the 4.8 Liter had 13 PSI of boost while the 408 CI engine had less than 8 PSI. Yet, they made roughly the same power. This is another example of how boost pressure will differ between combinations, yet will make similar power. I would guess that if we ran this supercharger on a 7.0 Liter LS that made over 700 Horsepower N/A, we would see little to no gain, even with the smaller pulley.

[@otm646]

Boost is a bad thing, it is wasted energy it is restriction to flow. The only thing you need to look at is lbs of air per min, mass airflow.

[@ericgarrison5097]

Not gonna lie dude, I sooo wish I had your job, or at least something close where I could Dyno test all types of parts on all types of engines. Don't get me wrong, I have my favorite v8's (LS & Pontiac 400/455), but I also like and seriously respect everything from coyote 5 liters, 3rd gen hemis to Honda K24a2's and Subaru EJ257's. Definitely gotta respect a little 4 banger 2.0/2.4 that'll rev from the factory to 8200-8500rpm, and put down 450-500+HP with basic turbo, rods and pistons. I'd love to see you testing some smaller, more common economy GM &Ford (LY7 3.6 and Ford 3.7L ) v6's and i4's, with aftermarket efi/TURBOS/superchargers/injectors etc these engines are putting down buku reliable power too. They put these in way more cars than LS's/LT's and can be had cheaper from junkyards, plus they fit soo much easier in smaller cars like Miata/s2000 and on and on. Engines like the last GM 60 degree v6's 3500/3900 are ridiculously compact and easy to swap, add a turbo, injectors etc will put down 500-600hp all day. Just saying that while I love an LS it's a pain in the ass to swap into a miata

[@InvincibleExtremes]

This is awesome, thank you

[@Crysmatic]

I like the torque curve better on the 408 with the smaller pulley. the hp on the 4.8 was still climbing with the 3.25" pulley. It'd be nice to see the hp nose over within the rev range. the s/c seems to work better with the 3.1" pulley.

Hey Richard. Love the channel. I'm really thinking about the torque storm due to it's relative low cost and good performance on my 5.3 ls, Delta reground SS2 camshaft, gapped rings, ported/polished 862 heads and Holley EFI 102mm TB/elbow/120lb injectors. I'm hoping for 650 rwhp in my foxbody. Talked with Torque Storm and he's thinks it should make good power but not 650. I watched the video on the 4.8 and it pumped out really good power. What is you thoughts? I'm a budget guy so I'd love to see a video of a Delta reground camshaft one day.

[@otm646]

You really don't want a supercharger on a modern four stroke diesel. Unless you are doing a Banks super turbo you're not going to gain any driveability on the street, or performance on the track eliminating the turbo. Load her up, let the boost rise and have her soak in 30+ lbs.

[@daviddroescher]

@@otm646 what turbo do you recammend that can spool over 5psig @55mph WOT 1150-1200 rpm in 6th gear(.61 OD Vs .69 w518) with a 1st gen Cummins (not modern)? Currently it is a hx35w12/6 with a BD Diesel Dieverter Valve "Quick Spool Valve" that turned the 12cm into a 6cm. Drop under 62mph@10psi and EGT goes through the and start dumping black smoke, due to the turbo falling off spool, this is were the belt driven shows promise. A 6bt @2500rpm uses the same CFM as a 4bt@3500. So was considering running a HE221 over a hx35/s360sxe, this is a 400hp setup on a 4bt@3500 so should erratically be perfect for my 6bt@ 2500.

I'm having trouble with a Torqstorm single sc in a 5.0 sbf with trickflow heads and cam, it wont boost, it reaches 5psi on redline. Tested no boost leaks, 3.25 pulley i'm afraid the engine flows more than what the sc can provide.

[@richardholdener1727]

the blower will support over 700 hp, you have another problem

[@Romelin]

Why does the stroker stroker get a intercooler and a fast manifold and the 4.8 didn't ? I feel like the 4.8 could've actually made the same power as the 408 stroker if those 2 variables would've been matched.
